If you're trying something new, have added an additional task or project to your plate, or are facing a challenge, please remember this:
It's always bumpy at the start.
It has nothing to do with you, and everything to do with the process of growth. You're learning, you're rebalancing, you're pushing yourself, you're evolving. It's not an indication that you're not capable, or that you should give up, or that you're not good enough, or any other false stories that pop into your head.
Hang in there. The road will smooth out. You just have to keep going.
