Without challenge, you can't fully grow. Without pain, you can't gain the strength you need to persevere, and when motivation isn't there, you're forced to DISCIPLINE yourself to keep yourself moving. When the work you need to do to move closer towards your goals is the LAST thing you want to do, you'll discipline yourself to do it anyway.
Now my point of this is we always want the right time, but the problem is sometimes there isn’t a right time and you just have to go for it. Seize the moment and strive to do better.
