Consider having a financial setback while attempting to do something such as start a business.
For instance, you may want to put a certain amount of money towards a particular goal, but you do not have the money to do that at that moment.
An absolutely great idea is, rather than get frustrated, if you don't have the willingness to drag something out for the money, see if instead you can use your current time to try work on other areas of business.
Let us consider a specific example of something like this: a guy lives with his parents, and wants to partake in Internet Marketing.
He may want a certain amount of money for more domain names, but his parents might be unwilling to give it to him at that moment.
That would be a good time for him to gather material for websites he would plan on, and therefore while partaking, his parents might see how committed he is to making this sort of idea a reality.
Therefore, he would have made better use of his time in that sense than if he would have used that time arguing with his parents, and the parents will likely take that into account.
Another example is if a particular person might not get government grants at that moment.
During this time, he could put forth more effort into his business so he might eventually have a better chance at getting government grants in the future if he presents his business plans specifically enough.
There are likely more examples you can think of, but take into account how important it is to get busy rather that get frustrated too much.
You'll likely be glad you did in the long-run.
