You know I have never come across such tools. I did get a chance to work with an entrepreneur who has ADHD, I served as his business adviser. Our setup was that he did not spend time on things unless we talked about it first and I held him to super tight schedules. It workout great! His tool sales business is doing fantastic here in Glendale,AZ.
On another note, I think every entrepreneur suffers from this but we call it drowning in opportunity! Lol.
Best of luck in all that you do!
You should use systems and tools that are intuitive and effectively designed with an emphasis on visual interfaces that minimise 'noise' and what your brain considers 'unnecessary' information . For example , pipedrive is much leaner than salesforce for keeping track of business opportunities . Simplify , simplify , simplify ! For the ADHD entrepreneur , business model canvas is so much better than a traditional business plan . Also surround yourself and delegate to extremely organised people around you . People who understand you and can follow up in your slipstream with organisation and ordered discipline . Visionaries and ideas people often have ADHD and its part of what makes them amazingly different . Happy to discuss if you want more help.
I have had to deal with that problem with myself all my life. Your only hope is practicing concentration on one thing and one thing only. If you continue allowing your mind to wander you will reach a fraction of the potential that you could have reached. With your problem it tells me you have a brilliant mind but uncontrolled it will cause you to have a lot less in life than you where capable of. You need to write what's the one thing you need to do today and follow that only no matter what. And the carrot for your mind is it can have whatever it wants if it will focus for the day. You have to convince your mind that it's in it's best interest and it's true, it's logical. Once your mind really gets use to focusing in one direction this will cause you to make $500 in a day rather than $50 and then it can do whatever it wants with all the money it will co-operate.
