Opportunities

Which of your business ideas presents the least risk and the most opportunity? This is something you should be watching out for on a regular basis. Listen when you communicate with others, really listen. See what data they are sharing, what they are talking about etc. If you get this feedback from a variety of stakeholders this will give you a good feeling for the biggest needs. Once you have the biggest needs (= opportunities) you know where to start. There are many opportunities for improvements in every field. What is it in your field? Where can you make a real, measurable impact? Watch out for it and make an impact!

Meeting the customer need

Are your projects focused on your customer needs or are they centered around internal process and system challenges or some other non-customer centric issues? Have you verified with the correct stakeholders that their perceived business problems are the correct problems to focus on?
Everything you do in a business environment should keep the customer benefit in mind. The customer should  be the North Star of every business. There are many other goals that are important but they won't matter that much when you have no customers.
Schedule your time with that in mind and always remember how you can communicate effectively with the customer to show them what you do for them.

The difference between Failure and Success

In many cases the difference between failure and success is just one more try. If a situation looks hopeless and you give up you have to decide if this is one of these situations or if it is the right thing to give up. It's not easy to say and only you know the right answer. When you try to reach an objective and fail you should change the approach though. Trying the same thing over and over and expecting different results is, according to Einstein, stupid. In any case not every objective is worth this kind of effort so think before you decide to reach an objective. Once you've decided that this objective is worth it and that you want to achieve it there should only be very few things (out of your control) that can stop you!
