You get only what you need.
“You can’t always get what you want / But if you try sometimes well you just might find / You get what you need” — The Rolling Stones, You can’t always get what you want
This is exactly true, especially during tough times.
What you need is almost always different from what you want. If you only focus on your ‘wants’ and aren’t aware of your ‘needs,’ you’ll get nothing.
Identify what you want and what you need. Grab what you need, and figure out how you can get what you want by using it. Don’t even expect that someone gives you what you want or what you need.
