If you set a goal for yourself and are able to achieve it, you have won your race. Your goal can be to come in first, to improve your performance, or just to finish the race -- it's up to you. - Dave Scott
Plant the seed of desire in your mind and it forms a nucleus with power to attract to itself everything needed for its fulfillment. - Robert Collier
The problem with planting, is that there are so many other conditions that have to be there, as well. I remember trying to "plant" seeds of positivity during a toxic work environment, but there were so many "rocky" barren obstacles.
How much impact it has I think depends on how much you want to get done. I grew up in a world where if you wanted it you did it. Others I have known grew up in a world with enough money to just buy it. Like oil and water the two don't mix. So for me pulling myself up by the boot straps is not that hard. Depressing yes but not that hard. Every carrot out of my garden has more value than one out of the store. I can't build a tractor (easily) so I had to buy one. The decision was difficult especially as I could use a new car. But the car won't do the things I need a tractor for. So for some if there is no money there is no option. They can not easily just do it. And our world is not geared to doing for yourself any more.
Packaging and advertisement sucks up more of your money than the product. A carrot out of your garden doesn't need plastic wrap and fancy writing to tell you where it came from. The more useless or unnecessary the product the fancier the packaging. Crome on a truck doesn't give it better mileage. So if there are times you can just do it, then by all means just do it.
But he doesn't mean it has to be work to work, only that you have to work at it. What ever your pace is fine as long as you are dedicated. Missing a few days is fine.
Confidence doesn't come out of nowhere. It's a result of something... hours and days and weeks and years of constant work and dedication. - Roger Staubach
