Some tips:
Take breaks between your devotion to your hobbies/projects. Do something else, for example start another hobby, then do your old hobby/project again as 'balance'. Get yourself a book from the library, or 2 so you can toggle them (But remember yourself to write a BIG note on the calender to when you have to turn it in!!!) Reading fantasy novels is nice balance for art/music, i found. At the time being i mostly read fanfictions, but they begin to get boring, as they all seem to copy from each other... Take a break from your hobby and take a walk outside maybe (enjoy and appreciate the nature?), talk to others(! - Es get energy from extroverting! Having someone do it with you can sometimes help you going through with it), etc. etc.
Often when i have to learn for university, i take occasional breaks where i take my guitar and just strum on it a few times while humming a melody... Then about 5-20 minutes after, i go to learning again. It's refreshing.
Listen to a radio in the background while doing your hobby/project, or have the tv on so you have something else to hear in the background. Listen to music while you do it. This way you also get new information and might see or hear something interesting...
If you have to do something and don't want to, then make it nice and interesting for you - imagine your hero X and by doing this you will achieve Y, or something silly like you are on your path to world domination and this is the first step, turn on music in the background, hang posters into your room that make you smile or laugh...
also: divide and conquer! I don't like ironing, but i often have to do it to get my shirts ironed... so i just trick myself and just take 3 shirts from the pile in the other room and take them to the room with the ironing board instead of the whole pile (if i take the whole pile i will think of all the work it will cause me that may be better spent doing less boring thinghs and then i won't do it). Then after those three i will decide again if i want to take another 3 shirts to the room. While having the radio on so that i can hear something that distracts me from the boring task of ironing my clothes. If someone passes by, i will sometimes start a light conversation with them (only light - don't want to get too distracted). I cannot watch tv while ironing, tv is way too distracting and then i forget that i have to iron my clothes 
I hope that helps you.
And if not... then I am sure you will come up with something
