There are a ton of ways you can create success in the areas in which you endeavor to succeed. The roadmaps, strategies, teachers, and support structures are everywhere. However, the only way you can be assured that you will NOT find success is if you throw in the towel.
I know it's hard. I know you have a workload both at home and at work that could choke a pregnant rhino. I know that you work with a few donkeys (and maybe even live with one or two.)
But none of that gives you an excuse to give up.
If you REALLY want to accomplish your goals -- personally and professionally -- you need to steel yourself for the inevitable storms that you will encounter. You WILL have "Calgon Take Me Away!" moments. You WILL be able to delineate all of the reasons why you should give up and the futility of your efforts. You WILL find some juicy moment that will give you permission to ditch it all.
DON'T. DO. IT.
Know that you are in middle of the squall, and it will pass eventually. Just keep breathing, moving forward and taking substantive steps to get a little closer to your vision. You can do this. You ARE doing this. Eventually, you'll look back and see that this was your greatest moment.
I believe in you.
