Pain and Pleasure
Learning a beneficial skill can be painful—especially as we navigate the process of doing something we've never done before; applying ourselves in a manner we previously thought impossible.
In the end though, we are usually grateful for the "new heights", and new possibilities that become attainable, as a result of the new skill.
Likewise, pleasure (though good and desirable) in excessive amounts, can weaken one's defence; lead to the unnecessary squander of resources, and establish a platform for long lasting addictions to occur.
Should we therefore, always seek pain, and ignore pleasure?
The answer to that question, is, "Balance and limits".
Life is supposed to be lived to the fullest, but with limits. Sometimes pain is only a harbinger of good things ahead.
Pain is NOT always bad. Pleasure is not ALWAYS good.
