I am an impatient driver. If I see a utility or garbage truck slowing traffic, I immediately start thinking of an alternative route to get to my destination. It may be out of my way, but hopefully I will save time by not waiting in line to bypass the roadblock.
There will always be obstacles to reaching your goals, and sometimes they will be unforeseen. Sometimes you'll be able to plan an alternate path to get to where you are going. Other times, you may have to be patient and wait it out. Once in awhile, something major will come up, and you won't make it to where you were going. You'll have to change your destination all together.
For example, I'm working toward writing full-time. However, I can't quit my full-time day job to pursue writing, because I don't have a surplus of cash, and it's pretty important that my children get to eat. Sometimes, I get really frustrated with work issues, and I dread going in. I read a Bible verse today that's going to keep me going though: "Teach slaves to be subject to their masters in everything, to try to please them, not to talk back to them, and not to steal from them, but to show that they can be fully trusted, so that in every way they will make the teaching about God our Savior attractive" (Titus 2:9-10).
So, for right now, I have to wait it out, and keep my eyes open for an opportunity to take a different path. What obstacles have to had to face when moving toward your goals?
