Sometimes, you're gonna go through stretches where it's really, really hard.
It's all temporary.
You can't get too high when it's good or too low when it's not so good. The only thing you really HAVE to do is just keep going.
Think of it as a tunnel.
You have to find the light and focus on the light. Even if it's just a little light or you can't even see the light at all – imagine the light if you have to – just keep going because there is a light. And once you come out of the tunnel there's this whole new world and you appreciate it so much more deeply than you did before you entered the tunnel.
