Just keep sowing seeds, planting trees, watering, ... while nurturing and learning planting techniques to ensure that the trees die less, grow quickly & yield high. One day when you are old & tired sitting under a tree, it could very well be the tree that you planted and cared for long ago. You deserve to enjoy the sweet fruits & cool shade.
In the first 5-7 years of your career, you should focus on planting. Young people nowadays have many who want to harvest but do not want to plant. Just think about it, do you want to harvest fruits without planting trees, investing time & effort to nurture them? Wouldn't that mean you have to steal? And even if you steal, you would still feel uneasy; having a lot of money would not bring you glory.
So do everything in accordance with nature, do not cunningly take shortcuts; sometimes the price you have to pay will be extremely high. Whatever it is, your capacity should determine what you can enjoy, that's the most fulfilling. Not having money is already suffering and shameful, but having a lot of money without knowledge is even more shameful.
