(Not enough Money) Am I in too much? (Overachiever???)?

Has your family said anything? If they can afford it without giving up too much then carry on with what makes you happy. Talk to them about it. If they are struggling then speak to them about it and decide which you can live without the most. Take a few more hours at work to help out a little more and to occupy the time you would have spent doing the activities, just think long and hard about the future and which would help you more in the long term. Keep the most fun, too!
