Maybe I have too much on my plate, but I have many different hobbies. I want to get /fit/,I want to learn a language, I want to learn music theory and I want to get good at playing guitar. And lately, it's been getting hard to manage my free time in order to actually progress in all of these things. I'm a student, so free time isn't a problem. The problem is me being a lazy faggot and playing vidya with friends or browsing 4chan instead of focusing on my long-term objectives.
Any tips to get shit done? Should I make a schedule or something?
Get less free time. You'll appreciate free time more and get more motivated to get shit done.
Get yourself a journal, a planner in which you wrote in concise detail all of your schedule to follow. Get a pocket sized, so you could bring it everywhere. Write on it each day, make a time for that. There are apps for smartphones to help you with schdeules, but you know that'll distract you more.
Also I'd advice you to drop some of the activities first. Like focus on one to get a visible result first then move on to make a new one. DOn't go chasing two rabbits at once and go home with none, better chase one and bring home one, you know?
