22 year old trying to start a business

Much like **bleep** said, be proactive. In my industry (painting), it's 10x better if I find flaws first and fix them rather than cut corners and hope my clients don't notice.  Because if and when they find flaws, they most certainly will fine-tooth-comb everything. Whatever you do, do it with integrity and be intentionally proactive.  I've built a successful business on this strategy and I keep getting referrals from my repeat clients.
