The only way to do it right is to do whatever it takes to do it the right way

Taking shortcuts doesn't always turn out right. Sometimes the steps you missed can be necessities in the end. If you want to have everything you will need when you get there then you will have to do everything along the way to have them. You have to accept that it may be harder than you thought. But if it's worth doing then it's worth taking the time to do it right. Sometimes just when you finish one thing you realize that there is something else that has to be done that you hadn't planned on.
