Sometimes it's like the RENDEZVOUS VIDEO CLIP above - you don't know what to expect OR what you're going to be confronted with - so one needs to be prepared for what MAY lie around the corner.
On the other hand it's all part of the personal and creative/technical development process - we all need to be able to spend time on our own to hone our skills, develop our practice/plans/strategies and our stamina.
"Going it alone" is necessary from time to time because there is no-one but ourselves to deal with - which in itself is a good thing! It gives us time to Review/Reflect/Plan/Check Resources - it provides us with an opportunity to 'Sober-Up' OR 'Wake Up & Smell the Coffee' and get real - Time for A REALITY CHECK ;O)
