The hard thing

1. Truly understand the "why"

Why should we adopt this new shiny language/framework/database other than that being ... well new & shiny ?

Why should we adopt Scrum other than that being recommended by ... so many gurus ?

2. Care to ask "what else ?"

Is this the best option we have, is there any other better option ?

Is this the only risk we have, did we miss any others ?

3. Spend enough time to figure out the "how ?"

and adapt it to our situation. The same idea can be implemented a bit different depends on the context.

4. Say "no" to ideas and especially to people

No to request

No to ... people (let them go)

5. Follow-through

Idea is good but execution is gold
