Help Needed! Having some tough times lately, promotions not selling…almost broke…
What is the best book/​audiobook you know on handling our own emotions/​fear of not being good enough/​fear of screwing up?

I don't know that the best thing to handle your emotions is to hole up with another book. If you've read any book on the subject, the answer is usually something like a few simple disciplines, repeated over time will give you unparalleled success in your particular pond.

I highly recommend Jim Rohn's Best Year Ever (you can usually find it on YouTube, the four hour version) in terms of how to structure your life.

As to emotions, these might be worth your time:

Make a list of ten things every day (it doesn't matter what. the idea is to get your idea machine going, eventually they have sex, some execution idea meets some person you want to help and you are off to the races)

Make note of (I think writing is best for this) at least three things you are grateful for each day,

Reach out to at least one person who has touched you in your life to acknowledge that person.

But I think the emotions might also take care of themselves if you find the right actions:

What are the one or two actions that would take your business forward if you did them consistently?

Create a structure to make those happen. I like what Josh Rhodes said above, but take it to a different level. Find some people who will not take your excuses and who will hold you to your word. No athlete who is worth anything doesn't have a coach, or a team of them. At the very least, some form of accountability partnership should be in place, even if it's telling your mother what you are going to do and giving her permission to nag you until it is done.

Shaq has his committee to help guide his action.

Andrew Carnegie had his Mastermind to keep him on track.

Last, you want to learn to deal with what's so. Instead of saying almost broke, which has all sorts of drama to it, write down your assets and debts and expenses. Define broke, and then make a plan for not being there if that's so important to you.

Also define “a lot of.” Some people think a month is a lot of time. Other's take years of concerted action and get that this is just the process. Some people think the ton of effort put into the first few promotions is “a lot.” Others get that this is just time learning and that you need a statistically significant sample before you can make any conclusions. How many have you actually done? How long have they run? What experts, or even colleagues, have provided you feedback? How many iterations have you made? Get the answers to those
