This is a general life rule.<p>The amount of hobbies I have started at and not enjoyed the first few sessions, then blamed not keeping going on my own persistence rather than admitting either A: it's too hard, or B: I don't actually enjoy it as much as I thought I would (Both of which tie in somewhat, people generally excel at what they enjoy).<p>The amount of times I used to blame any failed conversation on myself until a friend simply said (something along the lines of) "It takes two to chat". Also applies more generally to relationships, both of which can be hard to manage.<p>I'm sure there are many more examples, knowing your limits is key to being happy with your achievements.
