Steve has a garden that he's planted with seeds, and he needs to step back and let the garden grow. The garden can be watered and weeded; if you water too little or too often the plants will die. Weeding is a necessary process but understand that some weeds can be beneficial, others can be harmful (such as invasive species). Beneficial weeds can contribute to the diversity of the garden, so long as they do not detract from the primary seeds you planted.
A gardener must have patience and diligence to let the plants grow. When it is time to harvest, do not forget to enjoy the fruits of your labor. Celebrate what you have accomplished! And then, a winter will come (a void) after which you may plant some new seeds and the cycle continues.
Planting too many seeds at one time can make harvest more difficult. Planting seeds in the wild is more difficult because there are more competitors for water and light. There is value in sowing a few seeds in fertile ground, but there is also value in learning how those seeds will grow in less than optimal conditions. You may find that some seeds, surprisingly, will do well regardless of where you plant them.
