Choosing a soil mixture is never an easy task. I know this from experience. It's called trial and error.
Ideally your potting soil should be solid enough to anchor roots, but loose enough to allow quick root growth, good drainage, and the free flow of air (very important). It should also retains moisture without getting soggy.
Most houseplant potting soil must contain equal parts black loam, peat moss, and perlite. The black loam is quite heavy and provides a solid base of earth for the plant. Its finer particles, mainly clay retain nutrients. Peat moss is light and absorbs lots of water, keeping the growing medium moist. The perlite acts as a spacer so that roots can grow freely. It also keeps the soil from compacting and becoming waterlogged. If you want to moisten peat easily for the first time, use hot water. Only the first time.
You can become creative and use many other materials that can replace the three I mentioned above. For example you may use coarse sand and vermiculite are two of the common things. Or shredded bark and charcoal are used in special instances, like growing orchids. To replace peat moss, some gardeners use compost, decomposed leaves, or rotted horse manure.
But whatever works for you works, and don't fix it if its not broken.
Love is a temporary madness. It erupts like an earthquake and then subsides. And when it subsides you have to make a decision.
