Willing to be uncomfortable

If it doesn't feel like work, it probably isn't working. Simply accept it as part of the process; sacrifices will have to be made. There is a price to getting to where you want to go. Don't want to pay it? Then stay where you are. Your effort and excuse making are absolutely responsible for your success. Do the work, show up, do your best always and repeat until you die. Period.

That's what it takes!
