Time is precious and I know you have heard this over and over again. However people waste the present time being consumed by yesterday’s regrets and worrying about tomorrow. However no amount of regret will bring back the past and no amount of worrying will change the future.
Do not waste your precious time worrying about things you have no control over. Focus on today! Do things that will help you in the future and things that will heal you from your past. Live in the present moment, create amazing memories. Work hard towards your goals. Make sure that every you spend your days doing things that will help you and heal you.
