It seems a crucial resource is in short supply. You may turn out to have 'just enough', but you fear that, if one extra factor crops up or you make a single mistake, you'll be left in an awkward position. Nobody likes to live life this close to the edge, but the good news is you won't be in such a precarious position for much longer. All you have to do is be confident and clever. What you've got will suffice... as long as you don't waste precious energy or time, trying to be unnecessarily overcautious. Have faith in yourself. Everywhere you turn, you seem to come across reasons why certain things cannot be done, changed or even considered. Nor, though, can any of these things be accepted. Someone is refusing to recognise a solution. So entrenched has their mood of pessimism become that they almost appear willing to saw off the very branch of the tree on which they are sitting, just to prove that it is not safe to sit on! Soft words, and reassuring gestures are required, regardless of how tempting it may be to argue. What you want is a result, not a victory.  
You had best get a move on. There's a lot to be done. Though most items on your list are easy to deal with and some even come under the heading of 'fun', you may be hard pressed to cram them all in without compromising quality. Some corners you can legitimately cut, some niceties you can dispense with; some cakes can be baked but left without icing for now. Recognise the difference between these and the true essentials... even if the distinction seems inconvenient. You can come back and deal with details later.  
When you were small, a part of you didn't know much. Another part, though, knew plenty. Through your childhood you were taught to fill your head with facts and figures whilst ignoring your inner voice. Now you can hardly remember what you once knew so well. Every so often though, you get a whiff of it. A powerful dream. A sudden, intense emotion. Wisdom and intuition, from the very depth of your being, is now trying to reach up and communicate with you. Listen and be guided by an important inner voice. You know more than you think. Not only have you read, heard, absorbed and understood more than you realise, but you have your inherited memory to draw on. There are some things all human beings know, instinctively, if they stop long enough to listen to their inner voice. Your intuition is good. Your feeling can be trusted and the smattering of knowledge you have picked up, is not as you imagine .Do you have enough put aside for the rainiest of days? What if there's a downpour lasting months? Perhaps you'd best save more, just in case. What about the people you may need to count on one day? Will they forget their allegiance. Why not put them to the test now to avoid disappointment later? Insecurity not only breeds more insecurity, it eventually destroys things that are otherwise secure. Don't waste time in worrying about the future. Deal only with the here and now. It's all looking better than you think patchy as you imagine. You will gain impressive confirmation of this, if you respond to this opportunity confidently enough.
