Don't aim to do loads of things at the same time or in the future, pick something you can achieve now!
For example you can't go traveling due to uni commitments so don't worry about not being able to do it now. Set it in your mind as something you will do in the future.
However things like learning a language, learning to cook, reading more etc you could easily make happen!
Go to a book shop or if you are skint charity shops even have some decent books may take a bit of a hunt but there will be something, buy a cook book or search on the internet on cooking there is loads of info out there.
Join a club or society, hell my uni even has a sky diving club! There is bound to be something new for you to try, and they are an easy way to meet new people
