Wishing you’d tried something in the past can leave you with feelings of regret, wondering “Might I have succeeded? How would my life have been different? Could it have changed my trajectory if I’d taken a chance, worked a little harder, risked failure?” There’s only one way to deal with these feelings and questions and that’s to go for it without delay. You needn’t take unreasonable or dangerous risks, just be willing to leave your comfort zone. You’ll be far less likely to have regrets and, ironically, risking the possibility of failure is the most direct route… 
To success.
