At some points in our lives we seem to get stuck. I think it is when we get to the college age of 19-23, we have no idea what we are doing with our lives anymore, all of those ideas we had when we were kids seem stupid now and that if you did them, you'd somehow become the family disappointment. You might try something and still be a disappointment, but hey, at least you did it.
1. Take a different type of class that you would never think about taking.
I don't care if your major is medical, take that art class and learn something new, you may find that you are really interested in this and want to make a hobby out of it, or even a career. You can't make yourself not do something, in fear of disappointing others. You can't make everyone happy.
2. Move somewhere new
Now, this may seem as a bit of a stretch, but move out of your hometown and go somewhere new. Different opportunities arise in different locations.
3. Get a tattoo or piercing
If you are afraid of commitment and want to do something interesting, get one of these. Piercings are less permanent but you still have to commit to the idea.
Whether this be to another state or a different country, this will put your mind in perspective on what you are missing out on.
5. Get your own apartment
Stop living with your parents and make yourself be financially dependent. Yes, the comfort of home is nice, but you can't live with them forever.
6. Go to college in a different state
This will force you to get out of your comfort zone, you literally have no choice.
7. Go hiking
There is nothing more freeing than getting to the top of a mountain and being able to look out over the trees.
I don't care what you do, I just think that people sometimes get stuck and can't figure out what to do next, do something for yourself, do something that is going to make you get out of your comfort zone, this will most likely change you into a different person.
