Problems or challenges are either poison or vitamin

In our life, we will come across problems or challenges, inevitably and we cannot avoid them, unfortunately. Problems or challenges are not present to hinder our progress; rather problems are there to make us stronger, matured and resilient. Problems or challenges also mean we are at a crossroad where we have to make a decision. Problems or challenges are either poison or vitamin to us depending on how we view and readiness to deal with them. Bear in mind, rewards always await every success in solving each problem or in overcoming each challenge.
