Some things are better off kept to ourselves and not shared with others. If you share all the personal stuff with others, it might cause unnecessary confusion. Opening up about your secrets might lead you to question them and worry for no good reason. It can also make you seem like a pusher. Everybody needs a side that is just for themselves. That's the healthy way to go; no matter who says what.
If you share these, those around you will confuse you by offering other points of view, while you are surely moving towards your goals. We are all different from each other, and you won't get the same advice from everybody. Don't listen to everybody else and don't let your courage to be worn down. Walk towards your goals and know what you are doing; everybody will hear about your success, anyways.
Let the favors you did for people who were in a tough spot, charity and generosity be your own thing only. Those who are supposed to know do already know. Talking about these randomly might hurt some and also make you look like a douche. If you are doing good deeds only to be able to brag about them later, it is better if you don't do them at all. It really doesn't count in that case. Things may take a turn towards 'arrogance.' Take a moment and think this through: Why do you do really do nice things for others?
Nobody cares which diet you are doing, how you exercise or sleep, how often you have sex, etc. If you have some things in track in your life and are feeling happy about it, you shouldn't feel the need to establish dominance or make people jealous by using this. Don't live your life so that you can tell others about it. Everybody has their own way of doing things, as well as their own choices.
Talking about your moments of bravery and heroism is another thing that will make you look like a jerk. We are all faced with difficulties in both our inner and outer worlds and we somehow try to cope with them. Don't take yourself too seriously, everybody has their virtues. The most common noob mistake is telling those stories as if you weren't bragging about them, but just casually sharing them, sneakily boosting your ego. Just don't.
Everybody needs to believe in something to be able to go on with their lives in a healthy way. We all have things that make our lives easier and soothe our souls. Any kind of inferences you make from your life concern you and only you. They are only what you see from your own little window in life. In short, there is no need to share them or push them onto others.
The more you talk about these, the harder it will become for you to solve them. Some things are meant to be settled among those who have a strong connection with each other and are not to be exposed to others. Also, nobody can really help you to resolve anything. You will only be talking about those in vain, and f*ck up your own mood. Everybody will say something different, which will confuse you at the end. Nobody knows your family as well as you do. Trust yourself, be patient, it will be OK. It is just life...
Please, please don't be this person. Don't talk about the things you heard or saw about others, especially if you aren't completely sure about their truth. It isn't your business; don't show interest or think about such things. You will only wear yourself out by doing so, but most importantly, you will also lose the trust of the people who you go and tell such things to. They will be reluctant to share anything with you. There are much more important things in life; everybody should mind their own business.
Everybody is scared of something, and no matter how big and threatening it looks, we can all cope with it. However, asking for outside help will not bring you any use or comfort. On the contrary, no matter how close they are, people like using such things against you. The course of action is not looking for solutions by sharing your fears, but being aware of them and having the courage to face them.
Past is past, bringing it up again and again is useless, especially if it is all over. If any event that took place in the past and was ignored and kept bottled up feels like a big burden now, bringing it up again won't help anything. The best thing to do is to express your feelings while it is happening and share your thoughts on it. If you miss that opportunity, there is nothing else to do afterwards. You will only hold grudges and hurt others for no reason.
This is not taboo, however, there are such people that have zero consideration about their partner's privacy and spill everything, down to the tiniest detail. Although there are not many people who do this during an ongoing relationship, there are tons that do this after a break-up. They even seem to get off from trashing and embarrassing their exes. You also had very nice and special moments with your ex, so don't do this: don't lose yourself.
This isn't actually something you should keep a secret, but you should be proud of and show others. However, the reason why we include this here is that there are soooooo many people who go on and on about their talents and expect admiration. If you have a special set of talents and skills, don't talk about it, but show them when the time and place is right. They will see and appreciate your talents. There is no need to brag publicly.
