Confronting Reality

I find that holding certain assumptions can result in avoiding certain realities. The assumptions may be reasonable, but when the outcome is the denial or defiance of developing facts on the ground then those assumptions need to be questioned.
How and when to invest money in the building of my consulting practice is just such a quagmire for me. I assume the investment must decrease the longer it takes to become financially self-sustaining. Time being unquestioned negative feedback about my prospects.
But if the intial estimate of time required was an incorrect assumption, then to interpret what by nature may be a long process negatively is an enormous error. I need to be learning and adjusting as I go. The sooner I learn something, the sooner I can adjust.
Successful living and working requires the willingness to confront reality early and often, think through the implications and make adjustments accordingly. Am I listening?
