Whenever people tell me they are just not feeling it and don't feel inspired, I tell them to just get started.
See, the brain works in funny ways. And one of them is that you start thinking positively once you actually do something.
When you get started, your brain will think of ways to get something done.
It's that feeling you get when you finally decide to clean your house after postponing it for an hour. After 5 minutes, everything just seems like a mess and you're motivated to keep going.
Whenever you don't feel like doing it, actually do it. Take the first 5 minutes to do it. You'll see that you will actually do it.
And afterwards, you'll be thankful for yourself for actually doing it.
