UK visitor entry clearance application refused: impact on future travel [closed]

I am an Indian citizen living in Poland for the past 4 years for business. I never visited UK before.

I applied for UK visa few months ago in Warsaw to visit London for just 3 days, carelessly missed attaching couple of company documents related to my employment. After a month of processing, I received "refusal of entry clearance letter" which I summarize:

1. I have not provided evidence of employment and proved my source of income/salary (I only gave company registration document proving I am the CEO of company but missed attaching salary documents.). Because of this made them think that I am going to UK to find job and employment and I won't come back (which I concur). But they never cared to ask for missing documents, immediately gave the refusal decision which is terribly disappointing!

2. They say that despite my extensive travel history, the onus is on me to prove that I will leave UK. (I proved strong ties to my country India and second home Poland) with the number of travel stamps in and out. I am a frequent traveler to Europe. Also I sent them travel itinerary for 3 days, booking confirmed for hotel for 3 days, not enough?)

3. It also says that I cannot appeal the decision.

This is very disappointing taking into consideration that you pay GBP 180, they keep your passport for 1 month before making a decision, can't believe is such a long time.

I had shown them enough money, which is no problem being a business owner and I never had any intention of taking up jobs (why would I being a boss look for a job?), clearly this worked against me. I never been to UK before, so I thought I could visit London for 3 days.

I decided not to appeal (I had all the reasons stacked up to appeal through UK court within 60 days, money not an issue).

I see a black denial stamp in the backside page of my passport.

Now, all my hopes and travel plans of visiting UK, Scotland are destroyed and I vowed not to apply for UK anymore, as it was such a frustrating experience. I don't have patience to wait for 1+ month to reapply for UK visa. Even India is more advanced, issues e-visa these days much faster in about 3 days. What is killing me is despite living in Europe for 4 years, holding Schengen visa, UK visa should be easy, but I paid dearly.

1. Will UK denial also work against me applying for visa to any other countries?

2. What are the chances of getting UK visa again?
