What’s the best way to deal with negative thoughts?

On the days when I feel like a complete failure cause I got like 3 or 4 rejection emails for my poems and my bank account is almost in the negative. I do a couple of things.

1. Go for a walk or the gym to exercise the frustration out.

Or I write a list of new goals and manifestations.

I also remind myself that bad days are inevitable and temporary. Try to remind myself how much progress I’ve had the past 10 years and I’ve been through worst times and made it through the other side. Also,  at the very least,  I will have gotten inspiration for a new poem so, technically I still win. I also remind myself that rejection and failure are part of the process and have also been my greatest lessons.
