The thought has been credited to Einstein, so it must be true.
And it is, but it doesn’t matter, or at least it doesn’t matter as much as you might think, because what matters for your next step is not the skills you have today, the ideas you’ve had already or the attitudes you’ve had up to now.
No. What matters is what you do next, because what you do next will help to develop the skills you have tomorrow, to shape the ideas that occur to you next and even modify your attitude to life, the universe and everything.
In other words, there’s no reason to think you’ll be the same tomorrow as you are today, unless you resign yourself to staying in a comfortable rut of your own making.
The smallest action will have an effect – on you, your surroundings and your future.
So, the steps that got you here may not get you any further, but if you want to get further all you have to do is take the next step.
