Running a business is tough enough as it is. It's not surprising why many prefer to go into business with a partner in order to share the risk and workload. Unfortunately many partnerships have been proven to be unsustainable as they often run into countless of problems. I've never engaged in a partnership but I've seen others that have tried and failed. From witnessing these failed partnerships I've reached several conclusions. The biggest issue is that the partners have each got a totally different vision for the business. In such cases, there is no true solidarity and the partners eventually turn on each other at the first sign of trouble. Another huge problem is that one of the partners will often not come through on their commitments. Either they will not work as hard as promised or they won't come up with any latent capital that was originally agreed upon. As a general rule of thumb, it's best to avoid business partnerships. While there are successful examples out there, they are often in the minority. Have you had any experience with a business partnership?
