Always do your best. What you plant now, you will harvest later.
It is easy to get focussed on the future, and with all of the things you will accomplish someday. But if you are not doing something right now that is moving you in that direction, then someday will never happen. There is no more important moment than right now. Right now is all you have, right now. And this moment, and the decision you make in it, will determine where you will be in your…someday.
“But seek first the kingdom of God and His righteousness, and all these things shall be added to you. Therefore do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble.” Matthew 6:33-34
