Q: how do i make myself do something i really don't want to do, but have to anyway? (example: my spanish homework)
A: try to see if you can get to know the person who designed or created that particular assignment of homework. try to really get inside their mind and feel what they were going through. it's even quite likely that you just may see someone going through a similar struggle as you. by that point you will have formed a connection with this person, and you'll be easily driven to finding the answers that complete the other half of their endeavor
