Too many dwell on weaknesses it's a waste of time & life you cant be good at everything nobody can & nobody is. Become opinionated & don't be scared to do it, There are people just like you if you haven't met them yet it is just because you haven't met them yet trust me they are out there & as keen to meet you as you are them.
Love yourself & this is so important, How can anyone else love you if you don't like yourself? I'm not talking about conceit love yourself for who you honestly are. people are so much more interesting than they think they are. In fact if you are as mad as a box of frogs you are more interesting than somebody who isn't.
