When I was younger I thought quite often that I wasn't living up to the expectations of my family. If your feeling like that you just have to remember you have to do what makes you happy and more often than not your family will be alright about that. You need to remember that you can't live up to everyones expectations and you just need to be yourself and do what you want to do.
The way it can make you feel if your not living up to people's expectation is completely unhappy and you feel like your failing and you lose your self esteem and confidence, you have to do what makes you happy and not for anyone else and you aren't failing at all, your doing whats best for you.
We all have our own expectations that we want to live up to but you need to make sure you don't put too much pressure on yourself because it can make yourself feel worse if you don't achieve them. We all have goals and you can achieve them but try not to put pressure on yourself and take each day as it comes.
Expectations aren't always a bad thing just remember that everything might not turn out how you expect but it's still alright if it doesn't. Expectations can help you stay motivated to achieve what you want.
I hope this posts helps any of you and I think we all have some sort of expectations we want to live up to. What are your expectations?
