If you can’t handle stress, you won’t manage success.
I’ve said it a million times, you will hit bumps in the road and failures. If you cannot handle those difficult times and even if you do become very successful, you won’t be able to manage your successes! When starting from scratch, you have to be able to dig deep and grind through the tough times. They will come and your character will show if your up for the task! If you handle those failures and get back up, then you know you will handle the success when it comes!
