From public people

• Things should be made as simple as possible, but not simpler /Albert Einstein
• Reality is merely an illusion, albeit a very persistent one /Albert Einstein
• Everything seems impossible until it's done /Nelson Mandella
• Winners are simply willing to do what losers are not
• Multitasking is a myth: focus.
• Sometimes with two or three friends, and at other times I do solo trips. Those are the ones I enjoy most. Being alone with Mother Nature, aware that no one is anywhere close, knowing that you and only you can now care for yourself, is a great feeling. There are times when I just need to be alone, safe from anyone's intruding closeness. At such times I retreat into my beloved mountains. /Manfred Mornhinweg
• If you dare to do the most difficult thing that you can conceptualize, your life will work out better than it will if you do anything else. There is no way you are going to find out whether that is true unless you do it. / Jordan B. Peterson
