Its not a question of who is the man of the house, but who's the boss.
And whether DIYing or working a job, we all know who that is.
Arguing with boss on a paid job means you could lose job.
Arguing with boss on DIY, could mean losing benefits.
Measure twice, cut once.
Look at the nail, not the hammer. Watch the fence, not the blade.
If you hook your thumb over your belt you won't hit it with the hammer or leave it layin on the saw table.
