Having a Vision and having Ideas are very different things. Going off on tangents (ideas) can be fun, possibly useful for brainstorming, but most of us would like to see some sort of result, or progress at least.
A Vision gives us the landscape, strategic planners love models or written plans as that way the Vision becomes matter. There's 2 sides to this coin.
Naturally only having ideas doesn't lead to much. Over the years I have toughened up in that regard. Once upon a time when little Miryam was in ArtSchool having tons of fun for 5 years there was room for exploring and fluffing. The thing I regret about becoming older is that inherently it becomes more realistic and usually therefor less fun. Darn! But it shouldn't have to be. That's why it's important to keep the balance of having fun as well as knowing what you're really up against. Pink glasses are so yesterday.
So making the transition from ideas, to dream, to Vision, takes time, and both creativity and sensibility are needed. Just trying and seeing how it goes usually falters. Or the steam runs out if the Vision isn't strong enough (been there done that). Entrepreneurs or Artists that are most successful seem to possess the blend of several aspects that are necessary:
1. Talent: creativity
2. Vision: knows goals
3. Determination and conviction
4. Connector/net-worker: knows many people
5. Has financials in order
6. Web-savvy and use social media
7. Produce results
From what I can see online and observe in the real world; the ones that are "clued in" are savvy. They do their homework, take chances and go all the way. They stick their necks out, they pursue that which they believe in. Of course they have doubts about some aspects, as they are human, but generally they stick to their guns and ride the waves. They also are very good at building tribes (Seth Godin) which means they have a loyal fan-base and peers in their industry.
On this topic also read an excellent post by Roberto Verganti for Harvard here.
People that have done very well by following their Vision (imho):
Hugh Macleod: Gapingvoid art/wine/writing
Gary Vaynerchuk: wine
Chris Guillebeau: writer and traveler
Boh Runga: NZ musician and jewellery designer
Lucy : TheDesignFiles: interior decor blog
The future consists of adapting to new media, but to keep continuing 'the story' as that is vital to building the personable brand. Business has become personal, with communication becoming intimate. This also means transparency, ethics and being genuine are on the top of the list.
