Business is people
People are still just people. Sometimes they only act in their best interests. Its true, you rarely can do everything on your own, but when you choose people to work with, be sure you trust them. When you become more popular in the business community, and your business starts hitting the "big time" you'll be approached with a lot of offers. Hopefully by this point you have partners you trust and know well enough that you can work flawlessly with them. The new offers that come to you need to be well evaluated. Above all, be sure what is offered can be delivered.
It may even be that old partnerships or offers have a bitter taste in their mouth over your success. Rumors may spread, people might start voicing opinions. Just remember there are two sides to the tale.
Even the greats have had bad partnerships. They've had to let people go they thought were good for the company and in a few instances were even pushed out by the others, like Steve Jobs in Apple. In any case its important that your people are your people. Ones you have a good relationships with, trust, and can build something great with.
Just in the experience I've had (which could be considered short - although with a steep learning curve) I've seen many come and go. I've seen bridges burnt and new relationships turn out not to be what they appeared. I've seen offers pop up that were really just tools to get that particular person a little further up through someone else's established success. This doesn't neccessarily surprise me. People are people, and act as so. Perhaps my expectation that everyone has an agenda is what has kept me so understanding. I know others want success just as bad as I do, and sometimes are willing to do whatever it takes to get it. In my eyes, as long as those agendas are in line with mine, and their actions are legitimate, we're a happy couple.
I've said it many times before, but I'm going to say it again because it is so very true. I work with one of the best teams ever put together! I have some of the best advisers and mentors I could ask for. I have dedicated partners and the best friends in the world... Granted, we all have our faults and made mistakes, but our strengths compliment our weaknesses and we learn from one another. We've grown, built and created together, as a team and family. I cannot express via blog how grateful I am to have them in my life and involved in what I do.
I'd like to list you all, but I have a feeling you're already smiling because you know you're one of them. So to you, I say "Thank You!"
