Diploma in Interior Design? On Hold

So I was thinking, and got some feedback from boss. Maybe time-wise, it's not so practical now. Not so sure if I can squeeze 15-20hrs a week. I definitely have to have a very very supportive husband and him willing to take over some bb sitting jobs.. Now, that's not going to happen soon and perhaps I can start the course when Analina goes to school, at 3 or 4 years of age. That could also give me enough time to save that 5k right?? Meanwhile, I have 2 mini-design projects in hand (really really mini - some office shelving at the office) and working on tiles, marbles and granite... It seems interesting enough too! (on a later thought), it seems maybe a Diploma in Interior Design is not very appropriate for me at this point...... perhaps just stick to the work experience and I am currently swamped by quite a fair bit of details to work on! So, on the job itself, it's requiring me to put in extra time to learn new terms, new scope, and a lot more.. we definitely have a scarcity issue here, time scarcity!!! I only have 2 hands........... In addition to all these barriers, I almost forgot, my job here is only on a trial basis. By the end of the year, if the business do not take off, I won't have a job! So... yeah, I better put this on hold, and re-visit this issue next year Jan :P
