"Live your life without regret" is a quote I've heard often and many times have used myself. But how true is it really? All of us, every single one of us, have made mistakes in our lives. And all of us have made at least a few mistakes that make us cringe a little with regret. If it weren't for regretting these mistakes, we wouldn't learn from them... grow from them... and be sure not to repeat them. Just be sure you don't torment yourself about these regrets. We are but of only flesh and bone, sometimes we lack judgement in making decisions or believe we have everything figured out when we certainly don't.
So don't feel ashamed to regret certain decisions you've made. We all make them, sometimes more than once. It's what makes you human and not a robot. Find the beauty in it, laugh about it, cringe if necessary, all not necessarily in that order, and then when you're ready, quickly move the fuck on.
