If you want a successful, profitable business, you need to spend the majority of your time on profitable sales.
You might think that's obvious, but it's easy to forget on a day-to-day basis. It's very easy to get caught up in the chaos of getting jobs built. You have to order this, deliver that, call this sub, visit that supplier and the list goes on. Those things get the job built – and jobs have to get built – but they don't secure your company's future. Working on jobs pays your wages – it doesn't plan for your future.
If you're young and think your business will be just fine with you working on jobs, you need to know that at some point, your body won't let you work on jobs any more. When that day arrives, what will you do? If you want to be profitable, you need to hire employees or subs to build your jobs, trust them to do it well, and focus on sales.
Too many business owners sell a job, then build that job, then go looking for another job to sell. You can't continue like that for long. Never lose sight of the continual need to be collecting leads and making profitable sales. It's easy to get distracted, and it will cost you in the long run.
