The time allotted to each of us is precious and once it passes by, it returns no more. How we spend that time will make all the difference someday.
We cannot relive yesterdays; we can only learn from them. Today, we need to make the most of our time together and not take it for granted. Then, when each tomorrow comes, each yesterday will have been better spent.
Life is a learning process. Don’t be too hard on yourself. Improve as you go.
