The first solution to a problem is not to have the problem at all!
The second solution is to willingly accept the problem and see it as a challenge.
The third solution is to know that the problem is a bogeyman; it is not real.
The fourth solution is to know that nature has provided you the solution even before giving you the problem.
When it snows, there are no bacteria since herbs that heal you do not grow in that season. In the spring, the herbs come first and then the bugs. In the summer, the shade comes before the summer sun gets strong. So, nature takes good care of you!
