Ok.
Sure, personality is who you are, but what is the self?
If you look at the brain, the instrument of animal behavior, practically everything you think and do is just stuff that’s been seen, heard, felt etc or something ‘new’ based on those things. If you can define your personality as being lame, then here’s how to fix it.
It wont change overnight, but you can speed the change by doing the following:
1. Observe, learn and try to replicate the role/qualities/phrases/actions that the popular/cool/trendy/funny/likable/(insert positive noun here) do. Try to figure out the magic formula behind it all – you wouldn’t figure someone out overnight, but it is the process of trying to figure it out that gradually changes every aspect of your personality for the better. Write it down if you have to. Who you are, is a person who wants to improve, you aren’t selling out by learning from other people – after all, who you are has already been learned mostly from other people anyway. Now you can make a conscious choice to make yourself ‘the best of them’.
2. Identify the 'bad' things you say, try not to say them. Its like learning pickup lines or SS techniques, you sorta ‘memorize’ things you can say like cues instead of what you were going to say or do. An important thing is to find out the mechanisms that cause you to do those things. See a shrink if you’re daring.
3. Ask questions like you’ve been doing about how to improve it all.
