There are some basic principles that guide the decisions that I make as a coach and the things I emphasize
Training must be sustainable
Excellence is not made in 8 weeks, it takes time. It takes years of effort to really be great. So your route to success must be sustainable. Like the tortoise and the hare, rapid progress is typically unsustainable, either you can’t sustain the effort required and you get burnt out, or your body can’t recover and you get injured. The best progress is consistent sustainable progress.
Focus on what you can control
Your goals give you direction, they inform what things you need to do day to day in order to reach those goals. But it is those day-to-day things that are in your control which should receive the majority of your attention. You can control whether you ate the food that supports your goals, whether you did the training that supports your goals, whether you got your sleep, but you cannot directly control you achieving your goals. So you should focus your efforts on the parts you can control, the daily habits that will take you to those goals.
Always do what you can
Life makes achieving your goals hard. Whether it’s a tight schedule, limited energy, or an injury, things can make it difficult to continue toward your goals. You shouldn’t take an all or nothing approach, saying: “if I can’t do the optimal plan, I might as well not do it at all.” Doing something is always better than doing nothing. There will always be roadblocks on the way to your goals, and even more so with a more ambitious goal. You have a much higher chance of success if you do as much as you can given whatever circumstances you are in and adapt your plan to those circumstances you are in so you can consistently be making progress toward your goal.
