Like any homeowner, I have some projects that need to get done. Some I have the opportunity to do all on my own with the little free time that I have. Others, well, I'm no carpenter.
I lack the tools, the knowledge, the mathematical skills to make some projects come to life. Okay, let me rephrase that, maybe not "come to life" but I lack the necessary skills for them to be done right. Yep, that's better.
