Of course, we all have! Here are some practical tips to help:
1. Change your perspective: Walk away, do something different, you need to come back with a breath of fresh air and new perspective.
2. Change your input: Get some new information, read, listen, talk. Change your environment and stimulus to help get the mind going to help promote fresh thoughts.
3. Relax: Don't stress, you don't solve problems better when stressed out. Prayer or mediate, get your training session in, go for a walk, just take a deep breath! You'll think better and others around you will appreciate it too.
4. Try again: Don't worry if you didn't solve it yet. Get rested, refreshed and start the process over. There is a lot of value in "sleeping on it".
