Motivation is the hardest thing to get sometimes but here are some good tips that worked when i was depprest:
1.Just start it, this is the hardest part starting something but we have somthing in our barin that when we start something if we leave it it will be on our mind all of the time and u will want to finish it.
2.Make it eays to start for ex: if u play guitar get it in some place that if u just want to play it u can get it not somewhere that u have to spend energy do get it.
3.Make it look easy some people say when you say you make it looks easy but it is the only way that our brain will start to do something because we are lazy
4.If u want it really to make somthing put your self it to that position that if u dont something bad will happen for example bet money and if u achive ur goal u will lose that money, but this is somthing to fare but is the best thing that can drive you to do something inportant
