The real challenge is believing in abundance for myself, everyone else probably has gone through this that has made an abundant life.
I think one huge part of accepting abundance is being grateful, we can't say I deserve more! we just need to get to work. It's pretty easy to get down on myself some days about not being able to provide for me and mine if I ever did take the plunge and leave the corporate life for one of freedom. Some days are great, others aren't.
So the biggest work for me is mindset, losing the fear and worry, and just being grateful to be here now and have so much success in these first couple months :)
