The advice that I would give myself is just to persevere and be patient. Nothing happens in a day. Making a success takes just as much patience as hard work. Giving up after the first barrier is not an option. Push through and keep going.
Ten years from now, what would that version of yourself be disappointed by? I would be disappointed if I did not do all that I could to make this journey a success. I would not be happy to see myself 10 years later running the same rat race, being exhausted, and ultimately allowing my time with my children to pass me by.
If I keep doing what I do today, I will have a lot less of what I want.
What I am currently doing does not represent my capabilities. You never know what you are capable of until you have pushed yourself to your limits. I fully believe that everyone is capable of anything, you just have to make the mind shift to steer you in the right direction.
