You should not be satisfied with this. You can not just sit back and enjoy what others have done in the past. Just as others have toiled in the past so that you can presently enjoy the fruits of their labor, you must in turn plant for the future, for your children and generations to come. The planting of trees is a perfect demonstration that egotism has not set in. Fruits do not appear instantly, and effort is needed to assure that any tree bears good fruit.
Planting trees is an investment for the future.
On Tu B'Shvat, many have the custom to plant trees. The planting of trees indeed beautifies our land. As we mentioned in the last post, our trees are a valued gift from G-d. Whether we do or do not plant trees on Tu B'Shvat, we should remember that we are responsible for the future of the next generation. We must not allow ourselves to become blinded by our own self-worth.
