“The old you is only a shadow of the reality which is the new you. The shadow is useless without its reality.” Efrat Cybulkiewicz
Often growth is uncomfortable, which scares people away from going for it. You have to get moving to get growing.
You have to face the discomfort, so you can get out of where you have outgrown. You might not feel ready, but you have to go anyways.
You will never feel fully ready to go, being comfortable is well comfortable.
It will be uncomfortable to move, it will be new but that doesn’t mean it is bad. You have to be brave enough to take the first step and then the next few steps will come, and before you know it you’ll be in a full-on sprint away from where you used to be.
